## What is Electromagnetic EMF Detector?

This app is intended for entertainment purposes only and does not provide true electromagnetic and electrosmog detector functionality.
Track  magnetic  fields near you. A warning beep will be activated to warn you.
The app detects ferromagnetic metals using the iPhone's built-in compass feature. Also works as Electrosmog (EMP) detector.
Detect many kinds of home appliances that create radio-frequency EMF. For example:plugs,cell phones,routers, baby monitors, doorbells, intercom systems,night alarm clocks, electronic appliances , electrical wire, antennas. 
You can check the limit allowed in the "Radio-Frequency  Guidelines - for continuous and prolonged exposure" in the instructions button of this app.
The higher measures of magnetic fields are stored. Even the time when the measure was taken, so you can locate the source of magnetic emission.

Note: This app will not work on an iPod Touch, since it does not have a compass hardware. 

+++ FEATURES: 
-Track high magnetic fields and when has it been measured. 
-Table guide "Radio-Frequency Guidelines - for continuous and prolonged exposure".
-Warning beep near focus emissions. 
-Detect the strength of Magnetic force fields on all three axis’s (x,y,z). 
-Magnetic force is calculated in microteslas ( µ T ) 
-Record your readings with a time & date stamp of each event. 
-Store until 100 records. 
-Send measures by email. 

If you have any issues to report or suggestions to make, please email the device you’re using, iOS version, and a detailed description of the problem to bellostudios@gmail.com

### 4/5 — Entry Level for basics- see descriptor

*2025-11-26*

This app provides a good entry level tool more for learning the basics, with a meter in Microtesla, along with a standardized chart with risk ratings, value levels (Microtesla and Miligauss), and a short description. 
It will show values across the X/Y/Z horizon and definitely will capture the interest of kids and beginners alike.  It's not going to show accuracy to consistency ratios across wavelengths and such, but it gets the learning spark started for interested enthusiasts to learn higher grade spectrum analysis, easily done with SDR's and such. 
This is something crucial in an underserved industry in 2025 considering airwave multi-band over saturation as reported all over the country, as this tool serves a beginning fun little guide to learning that next level with basic SDR equipment to assess accurate levels of EMF harmful to health, and risk mitigation. Would like to see some references perhaps to basic SDR's to help point folks in that direction to help better assess safety in their neighborhoods. Makes learning the basics fun, should be standard issue on all new smart phones.

### 3/5 — Still deciding

*2025-04-25, version 5.4*

Still deciding

### 2/5 — Does not seem Accurate

*2025-02-05, version 5.4*

Since there are EMF readings for 3 axis, shouldn’t the X and Y swap if you turn your phone 90deg? My house generally averages about .7uT +/- .2 which is almost twice the recommended amount so I’m trying to identify the source.

### 5/5 — Only just downloaded

*2025-01-26, version 5.4*

So far so good only managed to check the microwave app seems to be pretty accurate

### 5/5 — Awesome

*2024-12-23, version 5.4*

Works great

### 5/5 — Great

*2024-10-22, version 5.4*

Works like a charm getting reading from areas in the home and shed as I have a pacemaker. Let’s me know where not to spend lots of time around appliances that have a high emf value

### 5/5 — Just opened it.

*2024-09-05, version 5.4*

I literally just opened it. Wants a review. I just opened it. That is my review

### 4/5 — yep

*2024-08-31, version 5.4*

seems to help fine them

### 5/5 — Awesome!

*2024-04-17, version 5.4*

Ohhhh I love it I love it I love it!

### 5/5 — Goods app

*2024-04-07, version 5.4*

Very good app

## Frequently asked questions about Electromagnetic EMF Detector

### What does this app do?

This app simulates the detection of electromagnetic fields (EMF) and electrosmog for entertainment purposes. It uses your iPhone's compass to detect ferromagnetic metals and can alert you to potential sources of radio-frequency EMF from common household appliances. It also provides a guide to radio-frequency guidelines.

### How does the app detect EMF?

The app detects ferromagnetic metals by utilizing the iPhone's built-in compass feature. It can also simulate detecting radio-frequency EMF from various home appliances. A warning beep is activated when it detects high magnetic fields or potential emissions.

### Is this app a real EMF detector?

No, this app is intended for entertainment purposes only and does not provide true electromagnetic and electrosmog detector functionality. It simulates these functions using the device's compass.

### What devices is this app compatible with?

This app works on iPhones that have a compass hardware. It will not work on an iPod Touch, as it lacks this necessary hardware.

### Can I track EMF sources with this app?

Yes, the app stores higher measures of magnetic fields along with the time they were taken. This allows you to potentially locate the source of magnetic emission. You can record up to 100 readings with a time and date stamp.
